A Novel Pd-decorated Carbon Nanotubes-promoted Pd-ZnO Catalyst for CO2 Hydrogenation to Methanol

Mechanistic Study of Carbon Dioxide Hydrogenation over Pd/ZnO‐Based Catalysts: The Role of Palladium–Zinc Alloy in Selective Methanol Synthesis

“…[8][9][10] Among these Pd/ZnO catalysts, which show good activity and high selectivity to methanol, are of a great scientific interest. [11][12][13][14][15] In order to improve the performance of catalysts for methanol synthesis from carbon dioxide, an understanding of the reaction mechanism, and the structure of the active sites, is of a considerable importance. Under a hydrogen rich atmosphere and at elevated temperature (≥150 °C), Pd/ZnO is known to form a palladium-zinc alloy phase, which is considered as providing the active sites for various catalytic applications including methanol steam reforming, reverse water gas shift, and hydrogenation reactions.…”

“…However, limited activity and poor selectivity to methanol due to the reverse water gas shift reaction (RWGS) have forced the investigation of alternative catalyst compositions, for instance: In 2 O 3 based materials; [1–4] palladium‐containing catalysts; [5–7] and gallium‐based intermetallic compounds [8–10] . Among these Pd/ZnO catalysts, which show good activity and high selectivity to methanol, are of a great scientific interest [11–15] …”

Cu-Mo2C/MCM-41: An Efficient Catalyst for the Selective Synthesis of Methanol from CO2

“…The chemical utilization of CO 2 , which is the cheapest and most abundant C1 resource, has become an important global challenge [3][4][5]. Catalytic hydrogenation of CO 2 can produce various types of valuable chemicals and has been recently identified as one of the most promising processes for the utilization of CO 2 [6]. Among these processes, the synthesis of methanol from CO 2 is important because methanol can be used as a starting feedstock for chemical industries as well as an alternative to fossil fuels [7][8][9][10].…”
